Vehicle-mounted lifting device

Technical Field

The utility model belongs to the technical field of for military use on-vehicle rescue is salvageed and is equipped, concretely relates to on-vehicle hoisting accessory.

Background

At present, the current rescue and rush-repair equipment of army has the problem that functional positioning is partially lost, the apparent not enough of rescue and rush-repair ability such as comprehensive properties weak, and army train dress wheeled vehicle weaponry is because of its protective capacities weak again, and undertake ammunition material transportation more, the weak task of defense links such as logistics support, consequently often become key striking object, and the high strength is used during the war, consequently, its probability that withstands war damage (trouble) is high, most train dress wheeled vehicle weaponry only can rely on saving oneself, limited means such as each other rescue are salvageed, and battlefield rescue and rush-repair task is heavy, extremely harsh to time limit requirement, this just brings serious influence and restriction for actual combat training and operation use, be difficult to satisfy the actual combat requirement.

Particularly, in the emergency situation that maintenance equipment is unavailable on a battlefield, intact parts and assemblies of a vehicle which is valueless to repair or seriously damaged by battle have to be disassembled and replaced on the vehicle to be repaired, and field hoisting operation is required when large and heavy parts are replaced, so that the rescue breakdown van integrated with the hoisting function can assist a repairing team in hoisting heavy parts, conveying equipment and equipment tools or moving the damaged vehicle; when the conditions of ditch falling of the light vehicle, overturning of the light and medium fault vehicles and the like occur, the hoisting operation can be carried out on site, and the fault vehicles are simply dragged and righted. Therefore, the wheel type equipment emergency repair vehicle applied by the army at present urgently requires that a professional heavy-load hoisting device with strong practicability and convenient and quick installation and use can be equipped, and the wheel type equipment emergency repair vehicle is used as a powerful support for emergency hoisting, emergency repair and towing tasks in wartime.

At present, most of vehicle-mounted crane cranes produced in China are small and medium tonnage cranes, and large-tonnage cranes are relatively few in production, however, with the development of society, the demand of domestic related industries on large mobile crane machinery is increasing, and with the rapid development of national economy, the demand of various engineering enterprises on the use of the vehicle-mounted crane cranes is increasing, and the enterprises hope that the vehicle-mounted crane cranes can be used for multiple purposes, namely, the vehicle-mounted crane is not only used for carrying heavy objects, but also used in different environments and different types. Domestic vehicle-mounted hoisting devices (mostly equipped on vehicle-mounted hoisting transport vehicles) are still mostly used in the engineering field at present, and are driven by hydraulic pressure, mechanical drive and electric drive. According to the rough classification of tonnage, 8-ton, 10-ton, 12-ton, 14-ton and 16-ton hoisting cranes and the like are common, a small-tonnage vehicle-mounted hoisting device is suitable for light-load hoisting and is convenient to drive, and a large-tonnage vehicle-mounted hoisting device has a large vehicle body because of a large body and is suitable for mountain roads and mountainous areas because the vehicle body is generally provided with a chassis with a short wheelbase and a large horsepower. The lifting device is divided into a straight arm telescopic type and a folded arm type according to the configuration of the suspension arm, the straight arm type has the advantages that the suspension arm has more sections, can be telescopic far, saves space when fully retracted, is easy to mount a chassis of the whole vehicle, and has the defects that the suspension arm configuration cannot carry out vertical lifting operation, and the lifting weight is relatively light; the folding arm type lifting arm is mostly formed by relatively folding arms (a main arm and an end arm, and some intermediate arms) and generally comprises a plurality of sections of arms connected by hinges. In the engineering field, the engineering vehicle-mounted hoisting device is researched and improved in the direction of a folding arm type hoisting arm capable of working at high and low altitudes, namely, a main arm of the hoisting device is increased and is closed to a straight arm form, however, the hoisting device is still heavy in size, and is inconvenient to disassemble, assemble and dispatch. Moreover, most hoisting devices neglect the research and improvement of the head of the boom, when the crane works on a rugged road, the phenomenon that the head of a connection load of the hook is easy to deflect is easily caused, and if the head movement freedom degree is not enough to ensure that a steel wire rope pulled from the head is always in a state of being tangent to the steel wire rope wheel, the head structure is easily damaged. For the emergency rescue task in wartime, the vehicle-mounted hoisting device can not be quickly disassembled, assembled and repaired, and also has the problem of easy damage of the structure, so that the vehicle-mounted hoisting device can not be applied to the emergency rescue in wartime, and a military vehicle-mounted hoisting device applied to the emergency hoisting in wartime needs to be specially developed.

The working process is as follows: referring to FIGS. 1 to 4, in the drawings,

the working process of the device is specifically explained in combination with the process of carrying out a wartime rescue and rush repair task by a military rescue and rush repair vehicle.

In case of emergency of unavailable maintenance equipment, the intact parts and assemblies of the worthless or serious war damaged vehicle are sometimes dismounted and replaced on the vehicle to be repaired on the rugged battle ground, therefore, when large and heavy parts are replaced, stable, fast and efficient hoisting operation needs to be carried out on site, even when some light vehicles cannot be started due to emergency, the hoisting operation can be carried out on site, and the simple dragging and righting operation is carried out on the light vehicles.

When a military rescue breakdown van loaded with emergency hoisting equipment in wartime meets a rescue breakdown task, parking is firstly carried out, then the whole van is supported by descending of an auxiliary supporting leg, then a hydraulic pump is started, a hydraulic system supplies oil to a hoisting device, an operator utilizes the expansion of an amplitude-variable oil cylinder 21 to roughly adjust the angle of a suspension arm 1 according to the characteristics of the position and the posture of a hoisting piece, the suspension arm 1 is controlled to lift by the amplitude-variable oil cylinder 21 and is hinged on a rotary platform frame 34, then a rotary driving motor 31 is utilized to drive a whole rotary mechanism 3 so as to drive the suspension arm 1 to rotate for a certain angle and approximately reach the upper part of a part, a conveying device or an equipment tool which needs to be hoisted, then a steel wire rope 43 (a fiber cable rope) pulled by a winch 42 is descended through a hoisting reel of the winch 42 so as to be hooked with a heavy object, and then the lifting and the rotation of the suspension arm 1 are realized through the matching of the amplitude-variable oil cylinder 21 and the rotary driving motor 31, then, heavier parts, conveying equipment and equipment tools are hoisted, the damaged equipment is subjected to part replacement type rush repair, or the damaged vehicle is moved to a position, and when the conditions of ditch falling of a light vehicle, turnover of the light and medium-sized fault vehicle and the like occur, hoisting operation can be carried out on site, and the fault vehicle is simply dragged and righted.

During the operation of lifting and dragging, the military rescue breakdown van can be positioned on a rugged road surface or even a slope surface inclined transversely due to the limitation of geographical positions, and at the moment, the vehicle-mounted lifting device is compact and simple in structure, light in weight, large in rigidity and strength and small in overturning moment of the connection part of the chassis, so that the military rescue breakdown van can still work normally to a certain extent, and the phenomenon that the whole van is inclined to a large extent so that the supporting function of the supporting legs is weakened and the lifting operation can not be carried out normally can not be avoided. In addition, in the hoisting operation, the wire rope 43 is drawn out from the winding drum of the winch 42, enters the pulley assembly 44 through the head socket 46, and is finally drawn out from the opening of the wire rope protecting cover 441, the head has one more rotation degree of freedom than the common hoisting equipment due to the existence of the head socket 46 and the socket 47, and when the head is inclined transversely, the wire rope 43 drawn out from the head of the suspension arm 1 and the head socket 46 can still keep the consistent vertical state, so that the force condition can be dealt with, and the head structure is prevented from being dragged and damaged and pressed and deformed due to the insufficient movement degree of freedom when the head deflects.

In addition, when the military emergency repair vehicle encounters the conditions of ditches, pits and the like and needs self rescue, the winch can be installed below the vehicle front side frame, so that the front end of the vehicle can have the rope hanging function. When saving oneself, earlier at the fixed connection capstan winch in a distance, rethread pulley assembly 44 goes out the rope direction conversion with wire rope 43, goes out the rope in the front side frame below, connects the capstan winch in a distance of connecting, and rethread plantago side frame below capstan winch output traction force is in order to realize saving oneself of military first-aid repair car, and from this principle, it can also be under other vehicle cooperations each other rescues.
